Saint Brendan was an Irish holy man who lived from 484 to 577 AD. Little is known about his life, and even his entry in the Catholic Encyclopedia is rather short. What we do know about him mostly comes from a strange tale called “the Voyage of St Brendan the Navigator,” written down in the ninth century and rewritten with various changes in several later manuscripts.

It’s an account of a seven-year journey he and his followers took across the Atlantic, where they met Judas sitting on a rock, landed on what they thought was an island only to discover it was a sea monster, were tempted by a mermaid, and saw many other strange and wondrous sights. They got into lots of danger, not the least from some pesky devils, but the good Saint Brendan used his holy might to see them through.

They eventually landed on the fabled Isle of the Blessed far to the west of Ireland. This is what has attracted the attention of some historians. Could the fantastic tale hide the truth that the Irish came to America a thousand years before Columbus?

Sadly, there’s no real evidence for that. While several eager researchers with more imagination than methodology have claimed they’ve found ancient Irish script or that places like Mystery Hill are Irish settlements, their claims fall down under scrutiny.

But, as believers like to say, absence of evidence is not evidence of absence, and there are some tantalizing clues that hint the Irish really did journey across the sea in the early Middle Ages. It’s firmly established that Irish monks settled in the Faroe Islands in the sixth century. The Faroes are about halfway between Scotland and Iceland. Viking sagas record that when they first went to settle Iceland in the late ninth century, they found Irish monks there. There are also vague references in the Viking sagas and in medieval archives in Hanover hinting that Irish monks made it to Greenland too.

How did they sail all that distance? In tough little boats called currachs, made of a wickerwork frame with hides stretched over it. One would think these soft boats with no keel wouldn’t last two minutes in the open ocean, but British adventurer Tim Severin proved it could be done. In 1976, he and his crew sailed a reconstruction of a medieval currach on the very route I’ve described. The boat, christened Brendan, was 36 feet long, had two masts, and was made with tanned ox hides sealed with wool grease and tied together with more than two miles of leather thongs. While Brendan says sailing it was like “skidding across the waves like a tea tray,” the team did make it 4,500 miles across the ocean. His book on the adventure, “The Brendan Voyage,” is a cracking good read.

Although Severin proved the Irish could have made it to America, it doesn’t mean they did. Severin had the advantage of modern nautical charts and sailed confident in the knowledge that there was indeed land where he was headed. So until archaeologists dig up a medieval Irish church in North America, it looks like St. Brendan’s voyage will remain a mystery.
